Chip is the general term for semiconductor component products. It is the carrier of the integrated circuit, which is divided into wafers.
Chip is an abbreviation of integrated circuit. In fact, the real meaning of the word chip refers to a little bit of large semiconductor chip inside the integrated circuit package, that is, the die. Strictly speaking, chips and integrated circuits cannot be interchanged.
Integrated circuits are manufactured through semiconductor technology, thin film technology, and thick film technology. Any circuit with a certain function is miniaturized and then made in a certain packaged circuit form, it can be called an integrated circuit.
Sometimes, we will confuse integrated circuits and chips. For example, in our usual discussion topics, integrated circuit design and chip design mean the same thing, and the chip industry, integrated circuit industry, and IC industry often also mean the same thing. In fact, these two words are related and different.
The difference and connection between integrated circuit and chipThe chip generally refers to the carrier of the integrated circuit, and is also the result of the design, manufacture, packaging, and testing of the integrated circuit. It is usually an independent whole that can be used immediately.
Integrated circuit entities often exist in the form of chips, because the narrowly defined integrated circuit emphasizes the circuit itself, such as a phase-shift oscillator that is as simple as five components connected together. When it is still presented on the drawing, we It can also be called an integrated circuit. When we want to use this small integrated circuit for application, it must be an independent piece of physical object, or embedded in a larger integrated circuit, relying on the chip to perform its role; the integrated circuit is more Emphasis is placed on circuit design and layout. Chips emphasize circuit integration, production and packaging. In a broad sense, integrated circuits, when it comes to industries (different from other industries), can also include various meanings related to chips.
Chips also have their own unique features. In a broad sense, as long as they are semiconductor wafers manufactured using micro-processing methods, they can be called chips, and they do not necessarily have circuits inside. Such as semiconductor light source chip; such as mechanical chip, such as MEMS gyroscope; or biological chip such as DNA chip. In communications and information technology, when the scope is limited to silicon integrated circuits, the intersection of the chip and the integrated circuit is the "circuit on the silicon wafer".
The role of integrated circuits1. Reduce the use of components.
With the birth of integrated circuits, small-scale integrated circuits have reduced the number of content components and greatly improved technology in discrete components.
2. Product performance is effectively improved.
Integrating the components together not only reduces the interference of external electrical signals, but also greatly improves the circuit design and increases the operating speed.
3. More convenient application.
One function corresponds to one circuit, and one function is concentrated into one integrated circuit. In this way, in future applications, any function can be applied to the corresponding integrated circuit, which greatly facilitates the application.
Common integrated circuits1. Metal-encapsulated integrated circuits
2. Power plastic package integrated circuit
3. Dual in-line integrated circuits
4. Dual-list surface-mounted integrated circuits
